I agree. A sibling thread showed an example of XML above containing params/param/value/int/ nodes which with attributes could just be <param type=int>.

I do agree that attributes/data was always a huge contention point on where things should go and caused confusion and bikeshedding.

I also saw a bit of this in the React/JSX community with decisions like render props, HoC, etc where it took a bit to stabilize on best practices.
